REVERSIBLE WINDOW.

Application filed February 26, 1919.

T0 all whom t ma@ concern.'

Be it known t at T, FRED FOURNIER, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Reversible Windows, of which the following is a specii lication.

This invention relates to a window construction, and particularly pertains to a reversible window mounting. It is often desirable to easily reach the outer surface of a window pane, especially when the window is being` washed and it is also of advantage to be able to reverse a window sash in order to supply it with a window pane. This is especially true when the windows are at considerable height and cannot be reached without danger.

It is the principal object of the present invention to provide a simple mounting for a window sash which will permit the window to loe readily opened when desired and will insure that it may be instantly reversed without the manipulation or removal of any parts and by direct action of the sash:

It is a further object of this invention to provide an automatic means for locking the window in position so that it will not rattle when closed and will not readily become displaced when opened.

Other objects of the invention will appear hereinafter.

The invention is illustrated by way of eX ample in the accompanying drawings, in which- Figure 1 is a view in front elevation, disclosing a window sash fitted with the reversible mechanism, parts of which are broken away to more clearly show the construction.

Fig. 2 is a view in vertical section on line 2-2 of F ig. 1, showing the complete sash mounting.

Fig. 3 is a View in section and elevation as seen on line 3-3 of Fig. 1, illustrating the lock provided for the window, and also indicating by dotted lines the reversed position of the window.

Referring more particularly to the drawings, 10 indicates a window frame. Mounted vwithin this frame is a sash 11, which sash is designed to normally close the opening in the frame and to rest against stops 12. Secured at the upper and lower ends of the sash rails and at the corners of the sash, are hinge plates 13 and 14. These plates pro- Specification of Letters Patent.

ject outwardly and are perforated to receive a reversing shaft 15. The shaft 15 extends through the perforations in these plates and may freely rotate. Fixed to the upper end of this shaft is a spur gear 16, having a lowerv hub which directly rests upon the plate 13.y F iXed to the lower end of the shaft is a spur gear 17 identical with the upper gear. The upper spur gear is in constant mesh with the gear rack 18 secured across the top of the window frame and disposed within a suitable recess formed for the purpose. This recess is covered by a shroud which has a forwardly and downwardly extended plate standing parallel and in spaced relation to the rack. This plate completely conceals the spur gear 16 and the rack 18, at the same time providing a guideway for a roller 2O which is mounted above the gear 16 and is free to rotate on the shaft 15. This roller acts to hold the gear 1G in constant mesh with the rack 18.

At the lower end of the shaft 15, the gear 17 is in constant mesh with a rack 21 fixed to the sash. By referring to Fig. 2, it will be seen that the shaft l15 does not extend completely through the gear 17 but is formed with a reduced portion 22 situated within a saddle member This saddle is formed with a cylindrical protrusion eX- tending into the gear and counter-bored to receive the portion 22 of the shaft, thus insuring that the saddle will move in unison with the shaft and gear as they travel along the gear rack 21.. The saddle rests upon a guide bar 24 fixed to the sill of the window. This saddle also has a downwardly projecting flange extending along the rear face of the guide bar 24, thus holding the gear 17 in mesh with the rack bar 21, at the same time allowing the saddle to slide along the bar.

' Reference beinghad to Fig. 3, it will be seen that side rail 25 of the sash is provided with a locking hool; 26 formed integral with a fastening `plate 27, this plate being coixnter-sunk within the side face of the rail and holding` the hook so that it will swing in a horizontal plane as the sash rotates upon the axis of the shaft 15, thus insuring that as the window is closed, this hook will swing into an opening in a lock plate 2S. The lock plate 2S is countersunk and secured to the face of the window frame adjacent the rail 25. Thus, when the window is closed and is in its normal posi-- tion, it will be locked against rattling andv may be further secured by means of any suitable window lock 29, this lock, of course,

being preferably mounted upon the opposite side rail 30 of the window sash.

In operation, it will be assumed that the window is closed and that the hook 26 is in engagement with the plate 28. 1f it is desired to open the window, the fastener 29 may be released and the window may then be swung outwardly upon the axis of the shaft 15. If it is desired to open the window and dispose it at any point in the width of the frame, this may be easily done by applying pressure to the shaft 15. This will cause the shaft to rotate and the upper and lower gears 16 and 17 respectively, to travel along their gear racks and in the direction of the arrows a, as indicated in Fig. 1.

Vhile the shaft is thus traveling, the roller 2,0 will bear against the inner face of the shroud plate 19 and the saddle member 23 will slide along the guide bar 24. At any point intermediate the extreme ends of the racks, the window may be swung outwardly and will pivot upon the shaft. When the shaft and gears have reached the opposite side of the window from their normal position, the window sash may be completely reversed and caused toassume the position indicated by dotted lines in Fig.

3. Vhen so reversed, it will be evident that access to the outer surface of the window pane may be easily had. When the window is to be closed, the shaft with its gears are moved across the window pane in a reverse direction and when they have reached the end of their travel the sash may be swung inwardly. This will cause the hook member 2.6 to register with the opening in the plate 28 and make contact in a manner to hold the sash against rattling and the latch 29 may then` be closed, if desired.

It will thus be seen that the sash mounting here disclosed, while simple in construction and capable of being easily installed, provides means for readily opening a window and permitting the sash thereof to be partially or completely reversed, as the occasion demands.

While I have shown the preferred form of my invention, it will be understood that various changes in the combination, construction and arrangement of parts may be made by those skilled in the art, without departing from the spirit of the invention as claimed.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. In combination with a window frame and its sash, hinge plates secured to the top p and bottom of said sash, and adjacent one corner thereof, a hinge rod extending vertically through both of said plates, a pair of Leanser;
